This is another great IIC/I2C/TWI/SPI Serial Interface. As the pin resources of FOR Arduino controller is limited, your project may be not able to use normal LCD shield after connected with a certain quantity of sensors or SD card. However, with this I2C interface module, you will be able to realize data display via only 2 wires. If you already has I2C devices in your project, this LCD module actually cost no more resources at all. It is fantastic for Arduino based project.
Commonly used in: copiers, fax machines, laser printers, industrial test equipment, networking equipment such as routers and storage devices.

Here's a handy Arduino shield: we've had a lot of people looking for a dedicated and well-designed data logging shield. We worked hard to design an inexpensive, yet sophisticated design. Not only is it easy to assemble and customize, also equipped with extensive documentation and libraries. You can get fast - to save the data to a file in any FAT16 or FAT32 formatted SD card, you can read any drawing, spreadsheet or analysis program.
We even have an example of how to use two free software programs to plot your data tutorials Including a real-time clock with the current timestamp for all the data so that you know exactly what happened when! Please note that this item does not come with an Arduino (you need to use the shield), or SD card.
It does have the RTC battery, however. Now, the geology of fire to all components of the welding and testing, but not installed head. You need some basic soldering skills to put it together, but even if you do not have much experience, you can get it within 15 minutes to complete SD card interface with FAT16 or FAT32 formatted card. 3.3V level shifter circuit to prevent damage to your SD card Real-time clock (RTC) to maintain the time, even when the Arduino is unplugged.
Backup battery lasted for many years Including SD card and RTC libraries and sample code means you can get fast Welded joints, circuits or sensors prototyping area. Built-in 3.3V regulator is a reliable reference voltage, and a reliable operation requires a lot of power to run the SD card Compatible with Arduino UNO, Duemilanove, Diecimila, Leonardo or ADK / Mega R3 or higher. ADK / MEGA R2 or lower is not supported. Package Included: 1 X Mini Data Logger; Battery not included
